Special universal guide screw M2x4 (x10)

The screw that keeps your guide securely fastened in every corner

When the guide screw loosens, the car loses direction, response, and consistency on track. This special universal guide screw, in metric M2x4 mm, is made of white zinc-plated steel and features a Phillips head for precise and controlled tightening without the risk of stripping the thread.

Function and performance

The guide screw is a small part with a critical role: it ensures that the guide remains attached to the chassis without play or vibrations. A worn screw, with a damaged head or compromised thread, can lead to anything from imprecise cornering response to total loss of the guide during a session. Preventive replacement is one of the simplest and most cost-effective interventions in slot maintenance.

The white zinc plating provides corrosion resistance and ensures that the screw does not seize over time, facilitating future disassemblies without damaging the chassis or the guide itself.

Compatibility and installation

As a universal screw, it is compatible with the vast majority of guides on the market that use M2 thread. Before replacing it, always check the condition of the threaded housing in the chassis: if the thread is damaged, it is time to repair or replace that area as well so that the new screw works correctly.

For tightening, we recommend using a quality fine-tipped Phillips screwdriver, applying moderate torque: it should be firm but not forced, especially on plastic or resin chassis.

Ideal for…

• Club preparers and mechanics who need to have maintenance spare parts always available.
• Hobbyists who perform their own preparations and adjustments on the workbench.
• Workshops or hobby shops with stock of basic parts for quick repairs.

Frequently asked questions

What type of screwdriver is used for installation?

A suitable fine-tipped Phillips (star) screwdriver for the M2 head. It is essential to use a tip in good condition to avoid damaging the screw head during tightening.

Is it compatible with all chassis on the market?

It is compatible with most guides that use M2x4 mm thread. If in doubt, check the specifications of your guide or measure the original screw you are going to replace.

Why buy a pack of 10 units?

The guide screw is one of the parts with the highest wear and risk of loss during maintenance. Having a stock of 10 units prevents unnecessary downtime in the workshop and is particularly practical for preparers working with multiple cars at once.

Does the white zinc plating affect the weight of the car?

The zinc plating is a surface treatment of minimal thickness that does not appreciably alter the weight of the screw. Its function is to protect the steel from oxidation.
